The actress — and new host of NBC’s “Love In The Wild” — says she has a “six month rule” about bringing new men into her only child’s life.

“I don’t introduce my son to anybody until he makes it to six months,” she told the Post today in Los Angeles. “So since I have been divorced (from actor John Mallory Asher), Evan has only met two guys — and that was in the past ten years.”

McCarthy, 39, has played coy for several weeks about her budding romance with the Chicago Bears linebacker. But she admitted today that while she would have participated in her new primetime dating show a few months ago, she wouldn’t now — because she is “interested in someone.”

After her split from Asher in 2005, McCarthy has had only a few serious relationships, she says — most notably with comic actor Jim Carrey.

“It took a while” to get used to being single, she admits. “I was like ‘Eww, I am so alone. I have to be with somebody. I can’t cuddle with Evan until he is 14.’ (But) I got to that place where I was like ‘I don’t really need anybody in my life. I am happy with myself.‘

“I said it in my book. I don’t need to have a lover to have love in my life. Then I finally got to that place and it kind of worked out.”
